I want a spot on my map where there will only be lasers and you will not be able to go to other places on the map and keep the flag. I got the zone code working so only laser flags spawn there but you can still just drive off with them.

Ya, the flagstay plugin will work. It's tricky, or at least I've always had trouble getting the zone right. There's no position and size like a box, you've got to say where the edges of the zone are in relation to the center. I usually look at this post when I put them in. I can never remember how they work.
